I find myself agreeing with Kwing, probably a good intro and outro. That said, your chord structure and melody writing are good all the way up to 0:52, where I'm wondering where that synth is going. What comes in is a mid-range melody, real slow, with a counter melody on top. Smart choice there. I see potential in you as a songwriter.

I'm just really not liking your drums. Was expecting something upbeat with that jolly little riff you bring up early on, and again at 1:46. Like, double-time of what you have here. Take that first measure of drums, speed it up by 2x, repeat first measure of that 3x, followed by your 0:39 phrase... That's what I was expecting, complete with perhaps a bassline.

All that said, your mixing is fairly crisp. Just super top-heavy since there is no bass.

Also, watch your chord structures down low, that they don't get too congested, block-chord style. Many people like to chuck as many notes in the low register as they can, forgetting that these notes are all so close in frequency that the notes actually interfere with one another, sounding dissonant and cluttered rather than massive and spacious. 1:54 chord is an example of this, though you've kept your instrumentation clean, so it's not as bad as it could be.

Song is a good start, but overall, it sounds incomplete. I'd like to see you revisit this some day.

Dawdles a little too much for my liking, and not just because of the slow tempo. This is too loud to be ambient, but not substantial enough to be anything else. As an intro or outro track to an album I guess it could work in a pinch, but I'm having a lot of trouble imagining where else a track like this would make sense.
